Air cooling apparatus



Patented Aug. 3, 1937 UNITED STATES PATENT OFFICE AIR COOLING APPARATUSand Application March 5, 1937, Serial No. 129,276

1 Claim.

This invention appertains to new and useful improvements in air coolingapparatus and more particularly to apparatus of this type especiallyadvantages of the invention will become apparent to the reader of thefollowing specification.

In the drawings:-

Figure 1 represents an enlarged side elevational view of the forwardportion of an automobile with parts in section to disclose theinstallation of the cooling system.

Figure 2 is a side ,elevational view of the compressor drive meansassembly.

Figure 3 is a fragmentary longitudinal sectional view takensubstantially on the line 3-3 of Figure 2.

Figure 4 is a longitudinal sectional view through the control means forthe clutch.

Referring to the drawings wherein like numerals designate like parts, itcan be seen in Figure 1, that numeral 5 generally refers to aconventional automobile of which the engine is denoted by numeral 6.

The cowl or dash wall is denoted by numeral I and to this is secured thefreezer unit I in association with the inter-engaging means 9. Numerall0 represents a catch pan disposed under the freezer 8 for catching anydrops of liquid falling therefrom especially when defrosting.

The compressor assembly generally referred to by numeral ll consists ofthe bracket structure l2 which includes the outstanding flange l3 uponwhich the compressor II is secured. The compressor shaft is denoted bynumeral l5 and extends through the compressor, being equipped at one endwith the fan l6 for cooling the condenser and at its opposite end withthe pulley l8 which is engaged by the usual fan belt I! of the engine.(See Figure 1.) Numeral 20 denotes the suction line between the filtertrap 2| and the compressor I4 while numeral 22 denotes the pipe linefrom the compressor to the condensef II. The pipe lines 23-24 extendfrom the trap 2| and condenser I! to the freezing unit 3.

A toothed clutch collar 23 is splined to the shaft l5 and is engageablewith the toothed collar 26 which is secured by a pin or other means 21to the shaft IS. A post 28 supports the bearing 29 through which theshaft 15 extends and the upper end of this post 28 has the arm 30 to 5which the upper end of the yoke 3| is pivotally secured, the yoke beingengaged with the splined collar 25 and has connected thereto the forwardend of the cable 32 which extends through the flexible conduit 33 andinto the barrel 34 which 10 is secured by the flange 35 and nut, 33 tothe instrument board 31. r A rod 38 extends into the barrel and isprovided with the hand knob 39 at its outer end. A pin and bayonet slot40 is provided between the rod 38 and barrel 34 so 15 that the cable orcontrol wire 32 can be held in either operated or inoperative position.

As is clearly shown in Figure 3, the shaft I5 is freely rotatable in thetubular stub shaft extension ll of the pulley l3 and by shifting the 20cable 32, the collar 25 can be brought into toothed engagement with thecollar 26 so that the pulley I3 is connected in driving relation withthe shaft l5 so that the compressor I4 is operated.

As is clearly shown in Figure 1, a fan 42 situ- 25 ated forwardly of theunit 8 serves to force the cold air rearwardly in the passengercompartment of the vehicle.

While the foregoing specification sets forth the invention in specificterms, it is to be under- 30 stood that numerous changes in the shape,size and materials may be resorted to without departing from the spiritand scope of the invention as claimed hereinafter.

Having described the invention what is claimed 5 as new is:

In combination with an automobile having a movable part, a coolingsystem including a freezing unit, a condenser and compressor connectedup in circuit with the freezing unit, a drive for 40 the compressor,said compressor including a shaft extending through the same and havinga fan at one end, said condenser being located in close proximity withthe said fan, a driven element connected with the moving part of theengine 5 and provided with a tubular stub shaft receiving the remainingend of the compressor shaft,

a clutch collar fixed to the stubshaft, a splined clutch collar on thecompressor shaft engageable with the stub shaft clutch collar, andremote 5 control means for sliding the splined collar into and out ofengagement with the stub shaft ELMER J.
